Surface Enhanced Raman Spectroscopy
Raman spectroscopy is the use of inelastic scattering of light to probe various properties of molecules and materials. Incoming photons interact with the electron cloud of the molecular bonds and inelastically scatter. During this scattering the energy of the incoming photon is shifted to red or blue depending on the particular process. This phenomenon is called Raman scattering and was discove...
متن کاملSurface-enhanced Raman spectroscopy.
The ability to control the size, shape, and material of a surface has reinvigorated the field of surface-enhanced Raman spectroscopy (SERS). Because excitation of the localized surface plasmon resonance of a nanostructured surface or nanoparticle lies at the heart of SERS, the ability to reliably control the surface characteristics has taken SERS from an interesting surface phenomenon to a rapi...
متن کاملBiosensing Based on Surface-Enhanced Raman Spectroscopy by Using Metal Nanoparticles
Surface-enhanced Raman spectroscopy (SERS) is a promising tool in the analytical science because it provides good selectivity and sensitivity without the labeling process required by fluorescence detection. This technique consists of locating the target analyte on nanometer range of roughed Au-nanoparticles. The presence of the metal nanoparticles provides a tremendous enhancement to the result...
متن کاملUnification of Surface Enhanced Raman Spectroscopy of Dyes Using One Pot Synthesized Stabilized Ag Nanoparticles
stabilized Ag Nanoparticles (NPs) were synthesized using Lee-Meisel method under three different conditions in an oil bath. UV-Vis spectroscopy of the Ag NPs showed a Localized Surface Plasmon (LSP) band around 430 nm, indicating Ag NPs had a size range around 40 nm. To fabricate a surface Enhanced Raman Spectroscopy (SERS) substrate, LSP properties of Ag NPs was employed with the goal of detec...
متن کاملSeeing through bone with surface-enhanced spatially offset Raman spectroscopy.
Surface-enhanced spatially offset Raman spectroscopy (SESORS) is a label-free vibrational spectroscopy that has the potential for in vivo imaging. Previous SESORS experiments have been limited to acquiring spectra using SERS substrates implanted under the skin or from nanoparticles embedded in tissue. Here we present SESORS measurements of SERS active nanoparticles coated with a Raman reporter ...
